用于$p$工艺研究的$^{92,94}$ Mo和$^{112}$ Sn上$α$诱导反应的横截面测量
Cross section measurements of $α$-induced reactions on $^{92,94}$Mo and $^{112}$Sn for $p$-process studies
摘要：
$^{92}$ Mo（$α,n$）$^{95}$ Ru、$^{94}$ Mo（$α,n$）$^{97}$ Ru和$^{112}$ Sn（$α,γ$）$^{116}$ Te横截面在8.2 MeV和11.1 MeV之间的$p$工艺伽莫夫窗口的上端处测量。我们的结果略低于全球豪泽-Feshbach计算的代码NON-SMOKER，但仍然在预测的不确定性。$^{112}$ Sn（$α,γ$）$^{116}$ Te截面与最近在相同能量范围内测量的厚靶截面吻合得很好。对于$^{92,94}$ Mo（$α,n$）反应，目前的数据接近反应阈值，可以消除以前的不确定性在20倍之内，我们现在可以提出有用的比较，统计模型计算不同的光学势。
英文摘要：
The $^{92}$Mo($α,n$)$^{95}$Ru, $^{94}$Mo($α,n$)$^{97}$Ru, and $^{112}$Sn($α,γ$)$^{116}$Te cross sections were measured at the upper end of the $p$-process Gamow window between 8.2 MeV and 11.1 MeV. Our results are slightly lower than global Hauser-Feshbach calculations from the code NON-SMOKER, but still within the uncertainty of the prediction. The $^{112}$Sn($α,γ$)$^{116}$Te cross section agrees well with a recently measured thick-target cross section in the same energy range. For the $^{92,94}$Mo($α,n$) reactions the present data close to the reaction thresholds could eliminate previous uncertainties within a factor of 20, and we can present now useful comparisons to statistical model calculations with different optical potentials.
